mama's SIGHTING DEVICE Filed March 14, 1962 INVENTOR. .ROBERT J. REYNOLDS W W ATTORNEY United States Patent 3,163,938 ARCIERS SIGHTING DEVICE Robert J. Reynolds, Montgomery County, ()hio (115 W. Lowery Ave, Dayton, Ohio) Filed Mar. 14, 1962, Ser. No. 179,684 2 Claims. (CI. 33-46) This invention relates to improvements in sighting devices. The invention relates more specifically to improvements in the type of archery sighting device disclosed in my copending application Serial No. 75,589, filed December 13, 1960. However, the invention is not so limited, and may be used with any type of sighting device adapted for ready attachment to, and removal from, an archers bow.

This application is a continuation-in-part of the application set forth above.

An archery bow is an extremely delicate and precise device, and when any attachment is made thereto it is preferable that said attachment not be characterized by massive fastening members or by screws, rivets or the like which require drilling or perforating or threading of the material of the bow. Such means of attachment may weaken or strain the bow in a manner to interfere with its satisfactory action.

An object of the present invention is to provide a sighting device which can be easily and readily attached to, and removed from a bow.

It is a further object to provide such a device in which attachment to the how does not require piercing, drilling, tapping or localized straining of the material of the bow.

It is a further object to provide a sighting device possessing the advantages of that set forth in said copending application and characterized by a considerable simplification in construction.

Still another object of the invention is to provide a device of the class described, which is light in weight, simple in construction, durable in use, and readily manufactured on a production basis.

Other objects and advantages reside in the construction of parts, the combination thereof, the method of manufacture, and the mode of operation, as will become more apparent from the following description.

In the drawings:

FIGURE 1 is a perspective view of a bow with a sighting device of this invention attached thereto.

FIGURE'Z is an enlarged exploded view of a sighting device of this invention.

FIGURE 3 is a fragmentary side elevational view, drawn on substantially the same scale as FIGURE 2, showing a sighting device of this invention attached to a bow.

FIGURE 4 is a sectional view taken substantially on line 4-4 of FIGURE 3.

FIGURE 5 is a sectional view taken substantially on line 55 of FIGURE 4.

FIGURE 6 is a fragmentary sectional view of the portion of the bow to which a sighting device of this invention is attached.

In carrying out the purposes of this invention, a sighting device is provided which has clamping means adapted to cooperate with a grooved section of the bow in securely but removably attaching said device to said bow without the need for screws and the like entering the material of the bow, and without concomitant piercing, drilling or threading of said material.

Furthermore, in said clamping means of the bow sight structural characteristics are incorporated which enable the accurate effecting of certain compensating adjustments.

Referring to the drawings in detail, and especially to FIGURE 1, reference numeral 16 designates generally a how sight of this invention attached to a bow 26. The how 20 has opposed surface portions 21 and 23, as shown in FIGURE 4. The bow 20 is provided with a string 22. The bow sight 16 includes a pedestal or base member 24 having clamping parts, herein further to be described, and, as indicated in FIGURES 3 and 4, engaging and cooperating with opposed comparatively short grooved portions or rabbets 26 and 28 formed in the structure of the bow 20 adjacent the surface portion 23 and adjacent the midportion of the how. The rabbets 26 and 28 are best shown in FIGURE 6 wherein only the how 20 is shown, without the bow sight 16 attached thereto.

The structure of the pedestal or base member 24 and associated parts will be more clearly understood by reference to FIGURE 2, wherein it will be seen that said base member 24 is provided with a channel-section portion 30 having inwardly tapered edges. The channelsection portion 39 is adapted to receive a corresponding dovetail-sectioned flange member 32 which comprises the rearward portion of an elongate scale or range member 34, whereby said range member 34 may be slidably positioned upon, and supported by, said pedestal or base member 24. A longitudinal slot 36 formed in the body of said base member 24 on one side of its median line provides a degree of resiliency to the walls of the channel-section 36, whereby the walls of the channel-section 30 may clampingly engage the flange member 32. A screw 38, passing through the body of the pedestal 24 on one side of the slot 36 and threadedly engaging the body of said base member 24 on the other side of said slot, enables the longitudinal position of the range member 34 with respect to the supporting pedestal or base 24 to be selected and secured at will.

The extremities of the pedestal or base member 24 are provided with extended feet or bearing portions 42. Each of said feet 42 carries a clamping member 44 secured thereto by means of a screw 46 penetrating said foot and threadedly. engaging the clamping member 44, whereby said clamping members 44 may be secured to said feet 42. Each of the clamping members 44 is provided with a projecting tongue portion or fixed jaw 48 adapted to extend around one side of its respective foot portion 7 42. Each jaw 48 is adapted to be positioned within one of the grooves or rabbets 28 formed on the sides of the. body of the how 20, as best shownin FIGURE 4.

Coacting witheach clamping member 44 and adapted to be secured thereto by means of a screw 50 is a movable jaw member 52. Each movable jaw 52 is formed to extend around the side of the foot portion 42 on the side thereof opposite its cooperating member 44'and to enter the opposite groove or rabbet 26 of the body of the bow 20. Thus, when the screws 56 are tightened, the associated clamping members grip the grooves or rabbets 26 and 28 and secure the pedestal or base member 24 to the body of the bow 20. Thus, the pedestal or base member 24 is secured to the how 20 without the need for drilling into the how 20.

The scale or range member 34 is provided with tapered side edges 60 adapted to receive flange members62 of an indicator or cursor member 64. The cursor member 64 is provided with a window 66 adapted to be aligned with any one of a plurality of range numbers or indicator marks or indicia 68. The range indicator marks 68 are shown as being applied to a strip 70 which is recessed into the scale member 34 or secured thereto in any other suitable manner. The flange members 62 of the cursor 64 are made slightly resilient in order to provide a slidable clamping action between the cursor 64 and the range member or scale 34. The cursor 64 thus remains in any adjusted position upon the range member 34, rendering any of the indicia 68 visible through its window 66.

Patented Jan. 5, 1965' To recapitulate the foregoing statements, it maybe said that there are provided two distinct longitudinally slidable mountings, one of the slidable adjustable mountings being that of the range or scale member 34 upon the pedestal 24, and the other slidable adjustable mounting being that of the cursor 64 upon the range member 34.

The indicator or cursor 64 is provided with a projecting block portion 74 which carries an elongate sight element 76 threadedly attached thereto and fitted with a head 78. Thus, said sight element 76 may be manually rotated for adjustment thereof within the block 74 so that the sight element 76 is movable transversely with respect to the scale or range member 34. The sight element 76 is provided at its extremity with a sight portion or pointer portion 80. Thehead 73 of the sight element 76 may be rotated to move the sight portion 80 toward or away from the center line of the cursor 64. The position of the sight member 76 is secured by a lock nut 84 adapted to engage the block 74.

The range numbers or indicia 68 are applied to the range member 34 in accordance with the action of the bow 20. This action or shooting ability of a specific bow 20 is found by experiment. The indicia 68 are then applied to the range member 34. Then, as seen in FIG- URE 2, the range numbers 68 indicate distances for shooting arrows with the bow 20. When, for example, it is desired to shoot an arrow a distance of 50 units, the cursor 64 is moved so that the window 66 thereof is in aligninent with the number 50,- as shown in FIGURE 2. The sighting element 76 is adjusted so that the lateral position of the sight or pointer 80 is at a desired position to compensate for any breeze or wind which may exist at the time of use.

Frequently, it is necessary to use a new string 22 in the bow 20 to which the sighting device 16 is attached. A new string may change the distance that an arrow will travel for a given angular position of the bow 20. Therefore, after a new string 22 is attached to the bow 20,

the bow is tested and the range member or scale 34 is axially adjusted with respect to the base member 24 to compensate for the change in the string 22. All that is'necessary to make such compensation is to move the range member or scale member 34 vertically to its newly desired position relative to the base 24. For such adjustment, the range member 34 is loosened with respect to the'base 24 by a slight loosening of the clamping screw 38. After the new adjusted position for the scale 34 is established, the scale 34 is firmly clamped with respect to the base or pedestal 24 by tightening the screw 38.

As shown in FIGURE 5, a plurality of register lines 88 are provided on the side surface of the base or pedestal member 24 for alignment with a suitable mark or marks 90 on the side surface of the scale member 34. Thus, should it be necessary to remove the scale member 34 frornthe base 24 at any time, the scale 34 may be reset to its desired position with respect to the base member 24, as shown by the register marks 88 and 90.

Although the preferred embodiment of the device has 4 been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
